ART oF MAKING PRINTlNe-SURFACES.

- SPECIFICATION forming part of `Letters Patent No. 637,595, datedNovember 21, 1899.

Application filed October 4,1899. Serial No. 732.439. (No model.)

To @ZZ whom, it may concern:

Be it known that I, EDWARD HETT, a citizen of the United States, and aresident of New York, (NeWDorp,) in the county of Richmond and State ofNew York, have invented certain new and useful Improvements in the Artof Making Printing-Surfaces, of which the following is a specification.

This invention relates to a newand useful improvement in the art ofmaking printingsurfaces suitable for planographic, relief, intaglio, orother printing:

In that branch of the art to which my invention is most nearly relatedit has heretofore been the practice in making printingsurfaces to lirstmake a basic surface by sticking up by hand and with great care a numberof transfers upon a flat support called a setting-up plate. Thesetransfers are usually thin pieces of paper bearing copies in black inkof the design or matter to be printed by aprinting-surface. The designson the transfer-paper are generally printed thereon and without anyspecial reference to the absolute or relative location of the designs onthe various transfer-papers. Where several printing-surfaces are tocooperate in printing, as in multicolor-Work, it is essential that thetransfers for each printing-surface be -Very carefully stuck upon thesetting-up plate in accordance with certain matching guidingmarkspreviously located on each transfer when the transfer is made and on thesettingup plate with reference to the register of the printing-surfacesWhich when completed are to cooperate in printing. When a basic surfacehas been thusA prepared, it has been the practice to lay it upon thesurface, generally a dat stone, which is to become the printingsurface.Scrapers are then passed over the setting-up plate, so as to exertproper pressure, and, the setting-up plate being removed, the transfersare found turned over from the setting-up plate upon the stone. Thetransfer-paper is then soaked off, but the ink of the transfer remainson the printing-surface, and the surface is then developed, as byetching, and thus ,becomes a printing-surface. In cases where itisnecessary to employ a plurality of printing-surfaces in printing a jobit has been the practice, according to this old process, to make each ofthe printing-surfaces in the same way, starting always with thesetting-up plate and the transfers turned over therefrom upon eachsurface to be made into a printing-surface. Whatever may be the numberof printing-surfaces required for a job, it was necessary to form eachin the same way from its particular basic surface previously preparedand with the same painstaking care, especially in regard to accuracy ofregister. Again, where in some cases it was desired to duplicate theprinting-surfaces, so that those Worn out might be replaced or so thatthe printing might proceed on dierent presses at the same time withduplicate printing-surfaces, it was necessary jtoiorm these duplicateprinting-surfaces ezh in the same way and always from a new and originalbasic surface previously prepared and each with the same expenditure ofcare, time, and labor. Thus the making of the printing-surfaces addedgreatly to the final cost of the j ob, and this cost increased inproportion to the number of printing-surfaces required.

The invention consists in its generic aspect in the process of making aprinting-surface, Whether planographic, relief, intaglio, or otherwise,from a previouslyprepared printing-surface, Which for convenience may behere called a primary printing-surface or a primary surface, by printingfrom saidprimary surface-that is, taking an impression in any suitablemanner from said surface-directly or indirectly upon or to a surfaceadapted to be developed into a printing-surface, said bodies or couplebeing arranged in a definite and predetermined cooperating relation bothlongitudinally and transversely with reference to prestablished guides,for the purpose hereinafter explained. The surface which thus receivesthe design from the primary surface I herein for convenience term thesecondary surface, and when developed the secondary printing-surface. Bythe use of the prestablished guides or guiding means, which may varywidely in character and arrangement, the design of the primary surfacemay be located on a secondary surface in an exact predetermined positionboth longitudinally and transversely and also with reference toregister, and from a series of registering primary surfaces a series ora plurality of series of regis- IOO ftering secondary printing-surfacesmay be made.

Y t in a prestablished seat in a printingLpress,

lmaking the primary surface, preparing fort this purpose a basicsurface, preferably by sticking up ordinary transfers bearing the`design to be printed upon a setting-up plate -and turning over thesetransfers in the usual so that they may be mounted at once in place inthe press and without any special adj ust-V ment for register be made toprint in accurate register.

'It' also consists in various steps and com-j binations of stepsconducive to the desired result and of more or less particularadvantage, as will hereinafter appear and be set out in the claims. d

In carrying out the process I may begin with a primary surface made byany suitable process or mayand generally do begin, as a preliminarytothe present process, by'rst way upon-a printing-surface, which is thensuitably developed and becomes the so-called primary surface. Thisprimary surface may be of stone, zinc, aluminium, or other suitablematerial and may be developed so vas -to be a planographic, relief,intaglio, or

in a machine in which the process of imparting -other printing surface.The primary surface is generally graduated--that is, the design thereonis so made as to be capable of printf ing .an impression in which theink will be distributed on the impression-surface in graduatedquantitiesfor light' and shade effects, `depth of color, &c. The primary surfaceand y secondary surface are then arranged in a definite andpredetermined coperating relation, so that the former works as requiredwith reference to the latter and with reference to the position whichitis desired the design of the v'primary surface shall occupy 'on thesecondary surface when imparted thereto. For this purpose the primarysurface and the secondary surface are arranged in prestablished seats'onsuitable supports prepared for them the design of the Vprimary surfaceto the secondary surface is most conveniently carried ont, thepreestablished guides being employed for quickly and with absoluteaccuracy arranging the primary and secondary surfaces vin their properycooperating relation. `The linked design of the primary surface is theny carried over from the primary surfacean'dimparted to or upon thesecondary surface directly or indirectly, but without the inter-mefdiate employmentof a setting-up plate. The

'secondary surface is then developed, so as to become aprinting-surface, and is then the socalle'd secondary printing-surface.

The secondary surfaces are made of a permanent size and shape to adaptthem to Like Y Athe primary surface it'may be of stone, zinc, aluminium,`or other suitable material and. may-be developed so as to be aplanographic, relief, intaglio, or other'printing surface,"a'nd thedevelopment of the secondary surface. vmayor may notbe in accordancewiththe method employed in developing the primary.

surface. For example, the primary lsurface may be arelief or intagliosurface and ythe secondary surface may be so developed as to be aplanographic surface, or vice versa. Neither the character or materialof one of thesesurfaces, whatever it may be, has any necessarydependence upon the character or primary surface maymteddirectly upon aconveying-surface, which is then brought into cp'I Ijjf''t'wthe'conveyin'g'jsu'rface beibnganintermediate between 'theprimarysurface andthe secondl lary surface and .beinga basic surface for thesecondary surface, or the primarysurface may be made toprint directlyupon the secondary surface, lin which case the latter'sur- -face whendeveloped wouldvprint Athe-same design as the primary surface, Vbut inreverse. VIn cases where an intermediate conveyingsurface is employed itmay, as preferred, be

in the'form of a fabric, as transferpaper, stretched over a suitablesupport "and be `brought into firm contactwiththe secondary surface andturned over thereupon, or the yconveying-surface may be a sheet ofpaper,

rubber, or other suitable material and Vheld `on a vsupport from whichthe conveying-surface is lnot separated when such surface is broughtintocontact with' the secondary sur `face,but which remains rmlysecured onits .support duringthis operation.' When the `conveying-surface is ofpaper and whether it is held on its support yduring the operation ofimparting the design to the secondary surface or is turned over fromitsA support upon the secondary surface, new or successive`conveying-surfaces must take the, place onvthe ,supe Vport of the oneused and preferably the iden- "tical place in imparting thev design tonew or successivesecondary surfaces. -v When the lconveying-surface isof rubber or some other material admitting of repeated use, it ispermanently held on'its support, the ink residuum, if any, beingl washedoff or otherwise 1removed before beginning its work vfor each -new 'anddierent design to be imparted to a vsecondary surface.

AI preferably-employ a conveying-surface in carrying over and impartingthe design to the secondary surface,the conveying-surface gen- 1erallfybeing of transfer-paper, and `afterrenceiving the design from theprimary surface `being turn-ed over-upon the secondary surface. Thesecondarysurfaces are preferably identical and interchangeable,especially where IOO IIO

they are to carry the same design, and Where they are to carry differentdesigns intended to cooperate in printing, as in multicolorprinting,they are designed and constructed for register when completed asprinting-surfaces. In using the conveying -surface in practice it ismounted in a machine with the primary surface and the secondary surface,the primary surface and secondary' surface being arranged in a definiteand predetermined coperating relation both longitudinally andtransversely, and preferably in the same or equivalent definite andpredetermined coperating relation both longitudinally andtransverselyrwith respect to the conveying-surface and with reference topreestablished guides. For this purpose I mount the conveying-surfaceand the coacting primary and secondary surfaces in the machine each inits own separate assigned place orpreestablished seat. The secondarysurface is made removable, so that successive secondary surfaces may bearranged in the same place, and thus be arranged in the same relationwith respect to the conveying-surface or successive conveying-surfacesand receive identical designs from the same primary surface, and whenthe secondary surfaces are identical the identical designs im partedthereto Will be identically placed, so that these secondary surfaces maybe interchangeable in the subsequent printing. The same result may beattained, however, by imparting a design toa secondary surface mountedin the machine in the particular` place assigned for it and thenmounting the neXt secondary surface in the same place occupied by theprimary surface, the primary surface having been previously removedafter having printed its design on the conveying-surface. In this casethe two successive secondary surfaces are arranged not in the same butin equivalent deiinite and predetermined cooperating relation withrespect to the successive conveying-surfaces. In making a series ofregistering secondary printing-surfaces designed to cooperate inprinting each secondary surface,being constructed and designed forregister, and its corresponding primary surface are arranged in the sameor equivalent detinite and predetermined cooperating relation withrespect to their conveying-surface. Moreover, in making a plurality ofsecondary surfaces from the same primary surface, whether through theintermediation of a conveying-surface or successive conveying-surfacesor not, the successive secondary surfaces are arranged in the same orequivalent cooperating relation with respect to the primary surface.After the secondary surface has received its imprint of the design fromthe primary surface and has been developed in suitable manner it maythen be inked, mounted in a press, and used as a printing-surface. Thusit will be seen that the printing-surface-viz., the secondaryprinting-surface-is made or derived from a previously-prepared.

printing-surface-viz., the primarysurface* and Without the intermediateemployment of a setting-up plate, which after the primary surface hasbeen made has no further utility. It Will also be seen that two or moresecondary printing-surfaces may be derived also from the primarysurface, and two or more secondary printing-surfaces, or one or moresuch surfaces with a primary surface, constitute a plurality ofprinting-surfaces adapted to be used in printing the same design. Thisplurality of printing-surfaces for the same design is very useful incases where it is desired to run two or more presses upon the same jobor when one or more extra printingsurfaces are required to take theplace of a printing surface orsurfaces which have been Worn out orbecomeimpaired by use in printing or otherwise. This plurality ofprintingsurfaces capable of indefinite multiplication or increase makesit possible, moreover, to print from such surfaces the same designindenitelyand beyond the limit of Wear of an individualprinting-surface. Again, from a series of registering primary surfaces aseries or a plurality of series of secondary printingsurfaces adapted tocoperate in printing may be readily made, the designs being impartedfrom Vthe series of primary surfaces to each series of secondarysurfaces in accurate and predetermined position and with reference toregister as printingsurfaces, and each secondary surface of a series maybe made identical and interchangeable with the correspond` ing membersof the other series. Moreover, much time, labor, and painstaking careare saved by the new process in preparinga plurality ofprinting-surfaces as compared With the old process of preparing eachprintingsurface directly from a manuallyprepared basic surface.

In the practical use of the invention a plurality of designs is imposedupon the primary printing-surface in accurate predetermined mutualrelation with reference to the printing of those designs by thesecondary printing-surface in accurate predetermined positions on theimpression-surface and with reference to register.Thispluralityofdesignsisgenerally imposed upon the primary surface bysticking up a plurality of ordinary transfers upon a setting-up plate inaccurate predetermined mutual relation which they are to have upon thesecondary surface. These transfers are then turned over upon the primarysurface, which is thereupon developed, so as to be capable of printing.The secondary surface has imparted to it from the primary surface thispluralityof designs in the same identical mutual relation. To accomplishthis result, I may bring the primary printing-surface and the secondarysurface into direct contact, or, as is preferred, I may impart thedesigns of the primary surface to a conveying-surface, from which thedesigns are then imparted to the secondary surface. Thus it will be seenthe secondary surface has imparted to it a IOO IIO

mined mutual relationand from a unitary plurality of designs in accuratepredetersurface bearing said designs in the same identical relation,theprimary surface or the conveying-surface being a unitary basicsurface with vrespect to the secondary surface.

The general procedure and the various detailsfollowed in practicallycarrying out the .VIS

steps of the process will hereinafter more particularly appear inconnection with the description of the mechanism shown in theaccompanying drawings.

In the drawings forming part of this specication I have illustrated acomplete machine capable ofv economically and readily carrying out. thevarious steps of the process above de- Y scribed.` Ihavealso'illustrated several modiications of mechanism.diagrammatically forthe purposeof indicating generally thatthe invention is not confined toany particular and specific form of machneor mechanism.

Of the-various types of machines Withwhich my process in itsl broadestaspect may be carried out I prefer to employ the completeorganizedmachine shown in Figs. 1 to 20,iin elusive. In' this type there areprimary and secondary surfaces and a conveying-surface. The machine-isorganized with special reference vto securing the desired manipulationand coperation of these three elementsthat is to say, there is mechanismfor bringing the primary surface and vconveying-,surface into coperatingcontact andmechanism for bringing the conveying-surface and secondarysurface into coperating contact, such mechanism being preferablyarrangedwith a View to securing the required register when the secondarysurface comes tobe usedl as a printingsurface. Inasmuch as a primarysurface and a secondary surface, with or without a' conveying-surface,have never'heretofore, so far as I am aware, been associated in adefinite and predetermined coperatin g relationship both longitudinallyand transrversely with reference to prestablished guides, so as tocooperate for the purpose of making a secondary printing-surface andlocating the design thereon in a definite predeterminedposition and withreference to register, it will be seen that the process may be carriedout by various types of machines or apparatus. e

In practicing the process in its most advantageous form the secondarysurfaces are cylindrical and preferably are shell-like and tulbular andmade removable from rotary supessary to insure that they are made tooccupy their prestablished seats on their supports. This the inventionprovides for. r

I will now describe the process in its various details by specificall ydescribing the particular machine shown in the drawings, omittinggenerally from' such description for the sake of clearness furtherstatements designed IIO to indicate what are and what are not theessentials of the invention in its more or less generic aspect. K

1 is the primary surface, cylindrical in form and preferably shell-likeand continuous and Vremovable from its supporting-cylinder 2,

which is secured on the shaft 3, turning in boxes 4. This primarysurface is suitably developed and when inked is ready to print thedesign which it is desired to carry over and impart to the cylindricalsecondary surface 5 on the support 6, secured on the shaft 7, whichturns in the boxes 8. The secondary surface 5 is also preferablycontinuous and removable from its support.

In Figs. 28 and 29 is shown the preferred arrangement for the secondarysurface. The secondary surface is there shown as a continuouscylindrical shell-like tube with a seamless exterior. The secondarysurface has a cylindrical support 6, the former having a slight interiortaper and the latter a corresponding exterior taper, so that thesecondary surface may be easily removed from its support, which contactswith and firmly supports every point of the internal periphery of thesecondary surface. In order that the secondary surface 5 may be readilymounted always exactly in its predetermined seat on its support 6,suitable guiding means for this purpose are provided, which insureabsolute identity and accuracy of position at all times bothlongitudinally and circumferentially. The guiding means forcircumferential location shown in the drawings consists of two oppositelongitudinal grooves 220 and 221, accurately cut on the exterior surfaceof the supporting-cylinder 6, and corresponding ribs 222 and 223, formedon the interior of the secondary surface and adapted to slide andaccurately fit in these grooves, a marked rib of the secondary surfacein a marked groove of the support. For the purpose of insuring identityand accuracy in the longitudinal position of the secondary surface onits support the support' is provided with a collar 224, screwed on oneend of the support to form a fixedabutment, against which one end of thesecondary surface accurately ts when in place on its support. Thesecondary form is locked in place against any accidental longitudinalmovement by the clamps 225 and screws 226 on the opposite end of thesupport. The support 6 is generally provided at one end, on which thecollar 8 is fixed, with ascrew 227, extending through a nut 228, adaptedto travel to and fro on the screw in the slot 229 in the support 6 andarranged to start the secondary surfacefrom its seat by the rotation ofthe screw. If desired, the support 6 may be so constructed as to beremovable from its shaft 7, the support being seated on the shaftagainst the collar 230 by keys 231 entering slots 232 in the shaft, and,if required, the secondary surface may be fixed permanently on itssupport, the collar 230 and the keys 231 serving as guiding meanswhereby the removable support may be accurately located bothlongitudinally and transversely in a predetermined position on theshaft. It is preferred, however, to make the secondary surface removablefrom the support 6. The primary surface is preferably arranged andconstructed in the same way.

9 is a shaft turning in boxes 10 and carrying the drum or support 11 forthe conveying-surface 12, adapted to receive an imprint from the primarysurface 1 and carry it over or impart it to the secondary surface 5.

The inking-frame 13, carrying the inking- Vrollers for the primarysurface 1, is fixed on the shaft 15, so as to be swung thereby to andfrom the primary surface. On the opposite side of the machine and fixedon the shaft 16 is the inking-frame 17, carrying the inkingrollers forthe secondary surface 5. The frames 14 and 18 for the damping-rollersfor the respective printing-surfaces are loosely mounted on the shafts15 and 16, respectively, so as to turn thereon when moved to and fromtheir printing-surfaces, as will hereinafter more fully appear. Theinking and damping frames and rollers for the primary andsecondarysurfaces 1 and 5 are similar and similarly mounted and actuated. Theirdetails will be described later on. Q

The main driving-shaft 19 of the machine is actuated from any suitablesource of power, as the electric motor 20, and carries the fixed gear21, which meshes with the gear 22,fixed on the shaft 23, which may becalled the power-distributing7 shaft, because the power for driving theprimary and secondary and conveying surfaces and inking and dampingrollers is derived from this shaft 23. For the purpose of thisdistribution of power the shaft 23 is provided with suitable clutches 24and 25. The clutches 24 and 25 are operated, respectively, by theclutch-shafts 27 and 28, provided with hand-levers 29 and 30. Theclutches 24 and 25 make fixed and loose the gears 3l and 32,respectively, on the shaft 23. The shaft 23 is carried in brackets 26,xed on the main frame. (See Fig. 2.) The gears 31 and 32 mesh,respectively, with the gears 33 and 34, fixed on the short shafts 35 and36, supported by the main frame and the brackets 37 and 38,respectively. The shaft 36 has fixed thereon gears 39 and 40, the formermeshing with gear 41, which is loose on the shaft 16, and meshes withidle gear 42, meshing with gear 43, fixed on the shaft 7, which carriesthe secondary surface 5. The gear 40 meshes with gear 44, secured to themain ink-distributing cylinder 45, which is sleeved to rotate on theshaft 16. The short shaft 35 on the opposite side of the machine fromshaft 36 has fixed thereon the gears 46 and 47. The gear 46 meshes withthe gear 48, which is loose on the shaft 15, and meshes with the idlegear 49, which meshes with the gear 50, fixed on the shaft 3, whichcarries the primary surface 1. The gear 47 meshes IOO IIO

`with the gear 51, which is secured to the mainl inking-cylindcr 52,sleeved kto rotate on the shaft 15. It will thus be seen that byAoperating the clutch 25 to lock the gear 32 onthe face.

yshaft 23 the secondary surface is driven through the train of gears 32,34, 39,41, 42, and 43 and Vthat the inking-cylinder 45 is likewisedriven through thetrain of gears 32,A

34, 40, and 44. It will likewise be seen that by operating the clutch 24to lock the gear 29 on the shaft 23 the primary surface 1s drivenVthrough the train of gearing 31,33, 46, 48,

49, and and that the inking-cylinder 52 ing-roller 59, which suppliesthe form-damp-l ing rollers and 61. Thus it will appear thatthese'inkingand damping rollers are driven with the secondary surface 5to supply that surface with inkand water as may be required indeveloping said surface into a printing-sur- On the opposite side of themachine i the inking and dampeni ng rollers are similarly arranged andgeared. The ink-distributing roller 62 carries a gear 63, which mesheswith the gear 51 and with a gear on the reciprocating inking-roller 64,which supplies the rollers 65 and 66. meshes with the gear 51 and with agear on the water-roller 68, which supplies water to the An idle gear 67on the frame 14l 3 rotates. By turning the eccentrics the`sl1aft,-vs'fi`thits printing-surface, is -moved laterally. Verticalvadjustment may' also be obtained by these eccentrics. They have slots93`and bolts 94 to lock the eccentrics in their adjusted positions. Theboxes 8 of the shaft 7 rare similarlyprovided with adjusting means. Inorder that the supports of cylinlders 2 and 6 may be lifted'from placein the machine orlowered into position, I provide pairs of lifting-armsfor each cylinderj2 and 6. The lifting-arms 96 for the cylinder 2areprovided with forks 97 at their upper ends to engage and supporttheshaft3 and at'their lower ends areprovided with racks V98. Thelifting-arms 99 for the cylinder 6 `are similarly constructed andarranged. y provided with the loose worms 100`and 101, adapted to belocated thereon by means of theclutches102 and 103, operated by thelevers 104 and 105, respectively. These'worms 100 Vand 101 engageworm-gears 106 and 4107 on Vthe shafts 108 vand 109, respectively, whichcarry two gears 110 and two gears 111.` The gears 110 mesh with theracks of the arms 96, and the gears 111 mesh with the racks of the arms99. vBy these means the lifting-arms are hoisted and lowered tofacilitate the lowering of the cylinders 2 and 6 vto place or tofacilitate the removal of these cylinders from place.

I will now describe the mechanism for operating thel support orcylinderll.

rollers 69 and UJ The 1n king and dampening rollers for theprimary/surface are for the purpos'e of supplying that surface with inkand water, so that it may print the design thereof as required. When theinking and dampening rollers are not required, they are swung back fromtheir printing-surfaces, but these surfaces may still be driven by theidle gears 42 and 49. The inking-frames 13 and 17 are swung back by theworm-shafts 71 and 72, respectively, having the hand-wheels'73 and 74.

These worm-shafts actuate the worm-wheels.

and 76, fixed on the shafts 15 and 16, on which the inking frames arerespectively fixed. The dampening-frames 14 and 18, carrying theirwater-rollers, are swung back,

from their printing-surfaces when. not required by the crank-shafts 77and 78, carrying, respectively, the cranks 79 and '80,con-

nected `with their frames by links 81 and 82. The crank-shafts aredriven by the gears 83 and 84, fixed thereon and actuated, respectively,by gears and 86, operated by the j The boxes 4for the shaft 3 areadjusted vertically in their re- A cesses in the main frame by the lowerscrews 89 and the upper screws 90, the latter working ,through arms 91,pivoted on the main frame, so that they may be swung aside whenthe-boxes are to be lifted from place.

For the purpose of lateral adjustment I provide eccentrics 92 in theboxes 4, in which the shaft on which is mounted the loosegear 115,meshing with the gear 116, fixed to the cylinder 11. A clutch 117,operated by they rods 118, which are actuated by the lever 119, servesto lock 'the loose wheel 115 on its shaft when the cylinder 11 is to berotated.

I will now describe the mechanism whereby the cylinder 11 is moved toandfrom the `cylinders 2 and 6 for the purpose of receiving animpression on its conveying-surface 12 fromthe primary surface 1 andcarrying it over to the secondary surface 5.

The boxes 10, (see Figs. 11, 12', 13, and 14,) which support the shaft 9of the cylinder 11, are capable of lateral movement in their recesses.Keyed on the ends of the shaft 9 and outside the Vframe are theeccentrics 120, `working in the vertically-moving boxes 121. Fast on theshaft 9, near one end, is the gear- 'wheel 122, in mesh with which isthe gear 123 on the shaft 124, turned by the hand-wheel 125. By turningthe hand-wheel125 the shaft 91s rotated and with it the eccentrics 120,whichas they turn force the boxes 10 in a lateral direction. Theeccentric-boxes 121 move slightly vertically in correspondence withthemovement of the eccentrics. This mechanism is capable not only of movingthe conveying-surface into contact with the primary and secondarysurfaces, but'also of applying to such contact allthe pressure required.Y

The shaft 19 is IOO will now describe the details of the inking anddampening frames. (See Figs. 7, 8, 9, and 10.)

The inking-frame 17 is provided with the bosses 126 to receive the shaft16, which carries the main ink-distributing roller 45 and on which theframe is fixed, as already described. The rider-roller 53 is carried inboxes 127, supported in recesses 128. The reciprocating rider 55 is alsosupported in recess 129. These recesses 128 and 129 are open at theirouter sides and are closed by the arms 130, pivoted on the main part ofthe` inking-frame by the bolts 131 and locked in place by the nuts 132on the bolts 133, which pass through aperturesin the lower ends of thesearms. When it is desired to take the rollers 53 and 55 out of the framefor the purpose of cleaning them'or otherwise, the arms 130 arennfastened and swung back, and the rollers may then be removed. Theboxes 127 are adjusted by the inner screws 134, having lock-nuts, andouter screws 135. The screws 135 pass through threaded apertures in thearms 130, are provided with lock-nuts 136 and hand-wheels 137, and haveheads 163, which rest in slots 164 in the inner sides of the boxes 127.Pivoted on the bolts 138 and preferably on the upper ends of the arms130 are arms 139, having forks 140 at their lower ends engaging grooves141 on the hand-wheels 137.

The outer adjusting-screws 142 pass through threaded apertures in thearms 139 and loosely through apertures in the arms 130. These screwshave also lock-nuts 143. 144 are the inner adjusting-screws for theroller 55 and have lock-nuts, as shown. The rollers 53 and 55 areiirstset by their adjusting-screws; but when it becomes necessary totemporarily separatevthese rollers from the form-inking rollers 56 and57, as when the machine is stopped for an hour or so, the hand-wheels137 are turned, and the rollers 53 and 55 thereupon separate from theinking-rollers 56 and 57. These rollers 56 and 57 are supported in therecesses 147 and 148, respectively, open at their outer ends. Theserecesses are closed by the arms 149, pivoted by the bolts 150 on themain part of the frame 17 and locked in place by the bolts 151 and nuts152. The outer adj usting-screws 153 and 154 for these rollers passthrough threaded apertures in the arms 149 and have lock-nuts, as shown.155 and 156 are the inner adjusting-screws for the rollers 56 and 57 andalso have lock-nuts. When the rollers 56 and 57 are to be removed, asfor the purpose of washing them or othery wise, the arms 149 areunlocked and swung back, when the rollers may be withdrawn. 157 is alever pivoted on a bracket 158 and operating to reciprocate the roller55. This lever has a lug 159 engaging an actuatingcam 160, rotating withthe roller 45 on the shaft 16, (see Fig. 4,) and also has a lug 161engaging a groove 162 in the roller 55. The inking-frame 13 and itsrollers is a duplicate of the frame 17 and its rollers.

The dampening-frame 18 (see Figs. 9 and 10) is provided with bearings165 to receive the shaft 16, on which, as already described, the frameis pivoted. The dampening-roller 59 is carried in boxes 166, which fitin recesses 167, in which they are adjustable by the inner screws 168,having lock-nuts, and by the outer screws 169, having lock-nuts andhandwheels 170. The screws 169 have heads 171, which work in recesses onthe inner sides of the boxes 166. The roller 59 has a gear 172, meshingwith the idle gear 58, carried by the frame 18, whereby thedampening-rollers are driven. The roller 59 may be withdrawn from itsboxes by retracting the journal at one end, which may be slid into arecess in thel roller by moving the pin 173 backward in its slot. Theform-dampening rollers apd 61 are carried in recesses 174 and 175,respectively, open on their outer sides, which are closed by the arms176, pivoted to the frame 18 by bolts 177. Bolts 178, passing throughapertures in the free ends of these arms, serve, with their nuts 179, tolock the arms in place. These rollers are adjustable and heldin place bythe outer screws 180 and 181, respectively, havinglock-nuts and passingthrough threaded apertures in the arms 176, and by the inner screws 182and 183, having lock-nuts. When it is desired to remove the rollers 60and 61, as for cleaning, the arms 176 are swung back, when the rollersmay be withdrawn from the frame.

I will now describe the specic construction of the supportwhich carriesthe conveying-surface 12. This support is shown in the drawings asacylinder 11 and provided with various accessories adopted forconvenience. It will be understood that this support or cylinder and itsaccessories may be variously modified and still carry out the mainpurpose of carrying over an imprint or impression from the primarysurface to the secondary surface. The cylinder is loosely mounted on theshaft 9, carried by the `boxes 10, which are supported by the main framebetween the primary and secondary surfaces, as already described. On theshaft 184 is carried a roll of a suitable fabric, constituting theconveying-surface 12,and preferably transfer-paper. The shaft 184 isjournaled in two extensible arms 185, provided with racks 186,telescoping with the arms 187 on the bosses 188, loose on the shaft 9. Ashaft 189, having gears 190 at both ends, which mesh with the racks 186,serves when rotated by its hand-wheel to move the arms 185, so as tocarry the rollin and out of the recess 191, formed in the cylinder, thearms 185 being locked either in or out by the spring-latch 192. Thebosses 188 have gear-teeth 193, meshing with the gears 194, fixed on theshaft 195, whereby the arms 185 and 187 may, when the roll is drawn outof its recess 191, be moved around the periphery of the cylinder 11, sothat the end of the paper maybe caught by the gripper-s 196, carried bythe rod 197 against an arm 214, on
